<h1>Pointer</h1>

<p>Pointer defines an unsigned 32-bit pointer. It is thought that this class was used by Macromedia's Generator product and 
its exact function is not known. It is included in the framework for completeness.</p>

field as a 16-bit integer. If the length is greater than 62 bytes then this field
is set to 0x3F and the next field, extendedLength contains the length of the
body of the encoded instruction.</td>

<h2>History</h2>

<p>The Pointer instruction represents the DefineBitsPtr tag from the Macromedia Flash 
(SWF) File Format Specification. It is not documented in later editions of the 
specification. It is not known when this tag was added.</p>
